judimasters, it's no different than the numbers that any manufacturer boasts on their websites, ads on TV, etc. I own a Volvo V70 that is "rated" for 28 highway, but I have never seen it.

Tesla makes its claims because they are true.

My lifetime average is 294 Wh/mi. That means that I've been averaging 289 miles per charge. Two days ago I drove 114 miles of errands and averaged 270 Wh/mi, or 315 miles per charge. I would say that Tesla's claims are quite realistic and easily achieved.

300 was the number under the "old" EPA 2-cycle measurement. 265 is the number under the "new" EPA 5-cycle test. Same car, two different tests. Tesla currently shows 265 on their Model S web page, so not sure what the beef is.

300 miles is certainly doable if you're careful. About 200-230ish depending on driving style, weather and road conditions(ie hills ect.) is more typical. Even so for everyday driving you plug up a lot when you're home or work. It's not like a normal gas powered car where you wait until a 1/4 tank to fuel up again.

95%+ of your trips in a year will be done in under 200 miles. On those rare occasions, simple careful driving will allow you a range in excess of 250 miles.

With added precautions, climate controls and speed adjustments, a range in excess of 350 miles is easily achievable.

The last so-called American made truck I bought had an EPA sticker on the window that claimed 27 MPG. In my experience there were too many twos (2) in the milage bragging, because I never got more than single diget milage on the highway. Learned that there is a huge amount of manufacturer puffing in those numbers. However, I can tell you that I have, with my P85 Signature, on several trips near Chicago, in Chicago traffic, gotten well over 300 miles on a single charge.

My range on Wisconsin freeways is somewhat less at 287 miles. But then, I didn't spend a lot of time tollway parked in construction watching the traffic on surface streets zooming by.

Lifetime average mileage for my P85 stands at 115 MPGe, or ~ 30% better than the EPA rating of 89 MPGe. To calculate your MPGe:

where EM is equal to your Wh/mi.

In case the above equation doesn't show up, here is the Wikipedia page:

A11: "I don't doubt your accuracy, but I was referring to Tesla's current statement: "Estimated range at 55 mph" is 300 miles.

See http://www.teslamotors.com/models/features#/performance"

And this is accurate. At 55 mph at standard temps I get over 300 miles. What are you trying to claim?

LMB spouse: indeed the trip computers only reflect energy used while the car is "on". I haven't checked, but I'd bet that it doesn't even reflect the energy used to preheat the car when preheating from battery (instead of shore) power.

Sorry A11, disregard please.
To Judi, the OP. At 55 I easily get 300 miles. What is your specific claim.

AmpedRealtor | 17 Janvier 2014

I've tried hanging garlic around my car, but it doesn't seem to work...

My lifetime average is up to 266 Wh/m. Before the very cold weather, snow and slush it was 256 Wh/m. Given a usable battery capacity of 81,1 kWh that gives 305 miles, in quite adverse conditions. Thus I think Tesla have every right to claim what they claim.

Interesting to note that JudiMasters hasn't appeared again in this thread and posted a single hyperbolic accusation...

judimasters | 18 Janvier 2014

@ Jewsh I posted that yesterday afternoon. I have other things I do besides sitting at my computer waiting for an answer. I am here now. What is the problem? I asked a question and got several KIND answer and one nasty gram.
